Question

if the empirical formula of two compund is NH and thier vapour densities are 15 and 30 respectively find the molecular formula

​

Answer 1

Explanation:

ANSWER

As we know,

Molecular weight = Vapour density ×2=2×15=30

Molecular formula = Empirical formula × n

n=

Empirical formula weight

Molecular weight

=30/15=2

so molecular formula 2×(CH

3

)=C
